The successful application of cellulase enzymes in textile finishing, particularly for bio-polishing and denim washing, hinges on a precise understanding and control of key process parameters. As a dedicated supplier of high-quality textile auxiliaries, we provide our clients with not only superior enzymes but also the technical expertise to optimize their use. This guide outlines the critical parameters for our neutral cellulase enzyme, ensuring you achieve the best possible results in your production processes.

Enzyme Activity and Dosage: The effectiveness of a cellulase enzyme is measured by its activity, typically expressed in activity units per gram or milliliter. Our concentrated cellulase enzyme is designed for high activity, allowing for lower usage rates compared to less potent alternatives. The recommended dosage for bio-polishing and denim washing applications generally ranges from 0.1% to 2.0% (owf - on weight of fabric), depending on the desired effect, fabric type, and processing time. Starting with a small trial batch is always advisable to determine the optimal dosage for your specific needs. We recommend consulting our technical data sheets or contacting our sales team for precise dosage guidance when you plan to purchase.

pH Range: The activity of cellulase enzymes is highly dependent on pH. Our neutral cellulase enzyme is formulated to perform optimally within a pH range of 5.5 to 7.0. Maintaining this pH level throughout the enzymatic reaction is crucial for maximizing efficiency and achieving uniform results. Deviations outside this range can lead to reduced enzyme activity or even inactivation. Therefore, using appropriate buffering agents and monitoring the pH regularly during the process is essential. As a reliable supplier, we can provide recommendations on suitable buffering systems.

Temperature Control: Temperature is another critical factor influencing enzyme kinetics. For our cellulase enzyme, the effective working temperature range is between 45°C and 55°C, with optimal performance typically observed within this range. While the enzyme remains active at slightly lower temperatures (down to room temperature with longer processing times), higher temperatures above 60°C can lead to rapid inactivation. Conversely, significantly lower temperatures will slow down the enzymatic reaction considerably. Precise temperature control in dyeing machines or washing equipment is vital for consistent outcomes. When you buy our enzyme, you are assured of a product designed for efficient operation within these established thermal parameters.

Reaction Time: The duration of the enzymatic treatment is directly related to the enzyme’s activity, dosage, and the desired outcome. Typically, bio-polishing and denim washing processes using cellulase enzymes can range from 20 minutes to 90 minutes. Shorter times may be sufficient for light effects or with higher enzyme concentrations, while achieving a more pronounced transformation might require longer processing periods. It's important not to exceed recommended treatment times excessively, as this could potentially lead to over-processing or undue stress on the fabric.

Inactivation: Once the desired enzymatic effect is achieved, it is crucial to inactivate the cellulase enzyme to stop the reaction and prevent over-processing. This is commonly done by raising the temperature to above 70°C for approximately 10 minutes, or by significantly altering the pH. Proper inactivation ensures that the final fabric properties remain stable throughout subsequent finishing and washing stages.
